ENANTIOSELECTIVE SYNTHESIS OF THE ALLEGED STRUCTURE OF NORPECTINATONE

The deoxypolypropionate 13 was synthesized from (S)-2-methyl-1-butanol by a reaction sequence featuring two highly ?-face selective organocopper/enoate additions 1 -> 4 and 7 -> 8.Neither 13 (the configuration of which was comfirmed by X-ray analysis of 8
